Commenting is one of the easiest ways to drive traffic to your site. Assuming you’ve got great content waiting for your visitors when they get there, it’s also a great way to initiate conversations and build community in your target market. You can use commenting to get the attention of and build relationships with other bloggers which might turn into JV partnerships down the road. And of course, allowing comments on your own blog gives your visitors, customers and referrals a way to connect with you and give you feedback about your content, products and services.
